Question

hey guyz
how r u all!!
What is double circulation??

Answer 1

A circulatory system in which blood travels twice through the heart in one complete cycle of the body is called Double circulation. In the human circulatory system, the pathway of blood from the heart to the rest of the body and back to the heart is called systemic circulation; and the pathway of blood from the heart to the lungs and back to the heart is called pulmonary circulation. These two types of circulation taken together makes Double circulation.
